Standard Test Method for Total Mercury in Water
1.1 This test method2 covers the determination of total mercury in water in the range from 0.5 to 10.0 μg Hg/L (1).3 The test method is applicable to fresh waters, saline waters, and some industrial and sewage effluents. It is the user's responsibility to ensure the validity of this test method for waters of untested matrices.
1.2 Both organic and inorganic mercury compounds may be analyzed by this procedure if they are first converted to mercuric ions. Using potassium persulfate and potassium permanganate as oxidants, and a digestion temperature of 95°C, approximately 100 % recovery of organomercury compounds can be obtained (2, 4).
1.3 The range of the test method may be changed by instrument or recorder expansion or both, and by using a larger volume of sample.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 A method for the disposal of mercury-containing wastes is also presented (Appendix X1) (5).
